GI3 Flashcards
best practices for paracentesis
- explain proceedure
- vitals w weight
- void prior to proceedure
- elevate head of bed
- monitor vital
- measure drainage accurately record, describe, lable and send to lab
- dress site, bedrest per protocol
- weigh pt and record difference
cirrhosis meds
INDERAL- beta blocker to help prevent bleeding ( reduces heart rate and hepatic venous pressure gradient)
Vasopressin and Sandostatin will reduce blood flow through vasoconstriction to decrease portal pressure
Sandostatin suppresses secretion of gastrin, serotonin and intestinal peptides which helps decrease GI blood flow
ascites causes
Increased hydrostatic pressure from portal hypertension
More plasma proteins are in the peritoneal fluid rather the vascular system. The liver does not produce albumin as well. This results in low protein in the circulatory system
The patient will have hypovolemia as well as third spacing in the peritoneal cavity along with edema
Massive ascites put pressure on the kidney which triggers the renin-angioretensin system. This causes sodium and water retentions which increases swelling
nutrition therapy for a pt w liver disease
low sodium, vitamins, high carb mederate fat, low protein
lab value abnormalities that increase risk of bleeding w end stage liver disease
elevated ast, alt, bili, PT, INR
decreased total protein, albumin
clay colored stool
inability of failing liver to excrete bilirubin
jaundice causes
intrahepatic obstruction from edema to the bile channels, elevated serum total bilirubin
hepatitis vaccines
A and B
Hep A risk factors
Spread most often by fecal oral route Flu like infection that may go unrecognized Oral anal or contaminated food or water Shellfish or food handlers Incubation period 15-20 days
Hep B risk factors
Blood and fluid transmission
Sex, needles, transfusions (now screened after 1992), Hemodialysis
Immunosuppressed more likely to develop
Incubation period 25-180 days
Many people with Hep B do not exhibit sx. If they do they might have jaundice, fever, joint pain, anorexia, N/V, RUQ pain, dark urine with light stool
Most adults who get Hepatitis B are able to clear it from their bodies and develop immunity
Small amount people do not develop immunity but become carriers
Hep C risk factors
Spread blood to blood
Blood or organ transplants received before 1992
Illicit drug use (highest incidence)
Unsanitary tattoos
Sharing intranasal cocaine equipment
Do not share razors, toothbrushes or pierced earrings
Average incubation period 7 weeks
May be asymptomatic for months or years after initial exposure
Acute infection not common
Most people DO NOT clear the virus and chronic infection develops
common signs of elevated ammonia levels (hepatic encephalopathy) stage 1
subtle, may not be recognized immediately
- personality, behavior, emotional, thinking, concentration
- fatigue, slurred/slowed speech, sleep disturbances
common signs of elevated ammonia levels (hepatic encephalopathy) stage 2
continuing mental changes
- confusion, disorientation to time, place, person
- asterixis (hand flapping)
common signs of elevated ammonia levels (hepatic encephalopathy) stage 3
progressive deteriorentation
- marked mental confusion
- stuporous, drowsy but arousable
- abnormal ECG, muscle twitching, hyperreflexia
- asterixis
common signs of elevated ammonia levels (hepatic encephalopathy) stage 4
unresponsive, obtunded, no asterixis
- positive babinski
- muscle rigidity
- fetor hepaticus-musty sweet liver breath
- seizures/death
